When tracking a stringline, keep the Tracker about 24 inches above
the string. At 24 inches the Sonic Footprint is about 6 inches in
diameter so keeping the Tracker over the string is easy. Just keep the
moldboard at the edge of the road where it should be, and the Tracker
should be over the stringline.
